Detailed ways

A kind of embodiment of the utility model is described below in conjunction with accompanying drawing 1-4.

The windshield clamping and positioning device of the cab has a gantry body 3 , and the lower end of the gantry body 3 is fixed in the concrete foundation 1 through the embedded parts 2 . The two columns of the gantry frame body 3 are fitted with a rotating sleeve 4 and locked with an adjusting screw 5. The rotating sleeve 4 is fixedly connected to a rotating arm 7, and the rotating arm 7 is fixedly connected to a supporting plate 8. The supporting The upper and lower ends of the plate 8 are provided with a positioning plate 9 for limiting the windshield 12 of the cab, and the rotating arm 7 is provided with a fixing plate 17, and the supporting plate 8 is connected with the fixing plate 17 as a whole through bolts; the positioning plate 9 It is fixedly connected with the support plate 8 by bolts. The end surface of the support plate 8 is provided with a clamp 11 for clamping the cab windshield 12 and the cab frame 13 from the back. Specifically, the clamp 11 includes an insert 15, a hook-shaped pressing plate 16 and an eccentric wheel 18. The support plate 8 is formed with a mounting hole 21, and the insert 15 fits closely with the mounting hole 21. A step hole 10 is formed in the insert 15, and the hook 19 at one end of the hook-shaped pressing plate 16 connects the back of the support plate 8. The windshield 12 of the cab and the frame 13 of the cab are clamped, the rotating shaft 20 at the other end of the hook-shaped pressure plate 16 is in clearance fit with the stepped hole 10 and passes through the stepped hole 10, and the eccentric wheel 18 is fixed on the end of the rotating shaft 20 Specifically, a protruding ring 14 is formed on the rotating shaft 20 , one end of the spring 6 abuts against the side wall of the protruding ring 14 , and the other end of the spring 6 abuts against the side wall of the stepped hole 10 .

When in use, take 12 sets of cab windshields and place them on the cab frame 13, then rotate the structure until the support plate 8 is firmly attached to the cab windshield 12, and use positioning plates 9 around the support plate 8 to pair the cab windshields. 12 positioning, rotating the handle to make the eccentric wheel 18 drive the hook-shaped pressing plate 16 to move to the left, so that the hook head 19 at the right end of the hook-shaped pressing plate 16 clamps the cab windshield 12 and the cab frame 13 on the back of the support plate 8, Then the spot welding machine can realize fast and convenient spot welding operations around the windshield 12 of the cab, which not only reduces the product damage rate, but also greatly improves production efficiency.
